VAIOR-GE NERATOB certain new and useful Improvements n Vapor-Generators,of which the folio 111 is a lull, clear, and exact description,rel-sluice being had to the accompanying drawings, formii'iga parthereof.

My invention has relation impro ements in vapongcncratois lor generati Qvapor from hydrocarbons used in lighti and heating or for otherpurposes; and consists in the novel details of constri more fully setforth in the specification Quilt pointed out in the claims.

In the drawings, Figure 1 is a front elevation 01' my invention moritedover a gasolene-tank; Fig. is a horizontal section on line 2-2 oi Fig.1; Fig. vertical tr 0 1s verse section on the line 33 of I Fig. 4 is anenlarged middle vertical sectional detail of the vapor generator andburner rounding the same.

The .0 eject of my invention is to construct a vapor-generator whichwill J'uply the vapor at the mint of consumption substantially a uniformpressure, so that rihere for example the vapor be used for ligh ngpurposes, the flame shall not fluctuate but remain practically constant.

A further object is to construct generator which may be readily attachedto a tank containing the hydrocarbon or gasolene to he vaporized; onewhich shall be compact, sim ple, and under ready control, and onepossessing further and other advantages better apparent "from a detaileddescription of the invention which is as follows:

Referring to the drawings T, represents a tank provided with a pipe pleading to any source of compressed air supply (not shown). Projectingabove the tank is a sleeve 1, the upper end of which is screwed to thelower open end of the generator chamber 2 ofmy improvement. Insertedinto the sleeve 1 nd extending up against the root of the generator 2 isa wick-holder or tube 3, said tube extending below the surface of thegasolene in the tank and having upper terminal notches or ports 1 forthe escape of the vapors into the chamber 2, or rather, into the spacearound the tube within the generator-chamber. Cast with the generator 2is a preheat- Specification of Letters Patent.

ing basin 5, said basin having formed with it an extension 6 serving asa connection and support for the hollow tee .7 whose inner horizontalarm connects with the passage c formed in the needle-valve casing 8 castwith or otherwise secured to, the generator 2 (Fig. l). The vertical legoi the tee 7 serves casing l'or the regulating necdle-valv 9, th icedneed -Ialve 10 in the cash a a in used to turn on or cut oil the supplyof vapor completely. The valve-stems are provided with operating handl sit as usual.

To render the structure compact it udll be seen (Figs. 1 2) that theclosed end of the mixing char er 12 tapers at the bottom so as to hebrought close to the burner 17.

In the operation of the device, and assuming the same to mounted asshown in Fig. 1, the feed-valve 10 is first closed, and some alcohol orother hydrocarl: on is poured into the basin 5 and ignited. The flamethus heats the walls of the valve-casing and generator 2. The valve 10is then opened, and the gasolene, forced both by pressure in the tank Tand by capillary attraction of the wick I/V, finds its way to thegenerator 2 the union, wher and air dischar cc it conducted thro d tothe uiiicnlte tion.

flashing into the burner. The

where itis vaporized by the heated walls, the vapors passing through thevalve casing S, tee 7, tip 11 into the mixing chamber, drawing in theair after it (see arrows Fig. 1) and forming a mixture ready for anyavailable consumption. A part of the mixture of gas and air becomesnaturally shunted through the pipe 16 into the burner 17, and escapesthrough the burner-tips 18. This escaping vapor is now ignited, theflame permanently impinging against the walls of the generator 2 andvaporizing the gasolene as it rises through the tube 3 into thechamliier 2. The hot vapor thus mixing with the air supplies the riser15 and may he used for lighting or heating purposes as desired. Thevalve 9 which may be termed the regulating valve is never completelyclosed, but is merely turned to position which will insure apredetermined delivery of the vapor into the mixing chamber.

The interposition of the wick between the generator and source of supply(tank T) serves to prevent any flicker in the flame due to variations ofpressure in the tank, since the supply of hydrocarbon due to thecapillary action of the wick is sufficient to prevent these variationsbeing felt at the point of discharge of the gasolene into the generator;and since the presence of the wick insures a substantially uniformdischarge, the flame will be constant. The wick therefore acts in thenature of a regulator and'controller of the supply of the hydrocarbon tothe generator, whereby such supply becomes uniform under varyingconditions of pressure in the tank T.

In lieu of a wick wire tubing'may be sub stituted for conducting andcontrolling the flow of the hydrocarbon from the source of supply to thegenerator. Where wire tubing is used the gasolene tank may be removedsome distance from the generator, and outof harms way, it beingpractical to employ wire tubing of any length.

Having described my invention, what I claim is 1. In combination with asource of hydrocarbon supply, a vapor generator, means for l l l l 1 lconducting the hydrocarbon to generator, a mixing chamber communicatlngwith the generator, a burner encompassing the,

upper terminal of the generator and located contiguous to the mixingchamber, means for shunting a portion of the gases from the mixingchamber to the burner, and means for regulating and controlling the rateof'delivery of the hydrocarbon to the generator, substantially as setforth.

2. In combination with a hydrocarbon supply tank, a generator chamber, awicktube leading thereinto, a valve-casing communicating with saidgenerator, a mixing chamber into which the valve-casing discharges, aregulating-valve for regulating the discharge of the vapor into themixing chamber, a burner contiguous to the mixing chamber encompassingthe upper end of the generator, means for conducting the mixture of airand vapor from the mixing chamber to a suitable point of consumption,and a shunt leading from a point beyond the 'mixing chamber forconducting a portion of the mixture to the burner, substantially as setforth.

3. In combination with a hydrocarbon supply pressure-tank, a wick-tubeleading therefrom and projecting out of said tank, a sleeve encompassingsaid tube, a generator secured to the sleeve and receiving thehydrocarbon delivered by the wick in the tube, a needle-valve casingcommunicating with the generator, a mixing chamber, a valvecontrolledvalve-casing communicating with the first mentioned valve-casing forregulating the flow of the vapor to the mixing chamber, a hollow unionreceiving the contents of the mixing chamber, an annular burnerencompassing the generator, and a shunt lead ing from the union to theburner, substantially as set forth.

In testimony whereof I ailix my signature, in presence of two witnesses.
